Mixing kerosene and Kleen Heat

I recently had a discussion with Scan Marine (Wallas Supplier) and spoke with Mike their technical guy. He now recommends that Diesel be run in the wallas. Our diesel used to be pretty bad but his explanation was that burning Kerosene or other fuels are not as fresh as diesel is. He also says that most of that stuff sits on the shelf for a long period of time. If any questions come about you might want to call the supplier direct. Most of the time they are willing to work with our customers!

Agree, excellent summary by Dan

Only difference being if I can afford a $50000 boat or a $2700 heater the difference of up to $100 saved on heater cost per season is not going to prevent me from using kleen heat verses uls diesel with the advantages of I've seen with kleen heat. Preventing the stink alone is worth the 100 bucks. Maybe we have USN (ultra sensitive nose) We use about the same amount as Dan in a season here in Wyoming.

Dan, I understand the lubricity value in my duramax especially with the ULS diesel, in fact I add Stanadyne year around for just that, but not the heater. Is it the pump or what in the wallas that needs the lub for a longer life.

Andrew, we sent our wallas to Scan Marine for repair and service this fall. Told them we had been using kleen heat since they last serviced in fall of 2003. They said it looked good inside and no problem continuing to use it.

I've heard it's the pump that needs the lubricity in the fuel. I use Klean Heat in my Wallas 1300 Heater, no problems for 2 years now (knock on wood), but then again, I believe I'm only just starting my 2nd gallon!

Thanks Dan.

That's the most thorough comparsion of the three fuels I've seen to date.

Dan---Thanks for the answer on the pump lub and good idea on the changing of just containers. Seems no matter what, when I'am messing with the diesel there's always alittle spill somewhere. Put a 56 gal tank in my pick up just so I wouldn't have to fuel it so often.

Dan,

Let me know if you find that source of Kleen Heat at $4/gallon!!!! Home Depot has it at $9 plus here in the Portland area.

My understanding of the Wallas is that it is a "drip pot" type of burner. That is that the fuel drips into the combustion chamber and the heat helps to vaporize it, and then it burns. The draft is forced by the fan, and this helps to prevent back drafts, which can be a problem with drip pot stove burners.

One of the potential problem with diesel, is that it may sit in a tank for an unknown peroid of time--so it is best to obtain it from a dealer who has a high volume. The longer it sits, the more likely there is to be contamination from algae. (generic) We have settled on Kleen Heat because there seems to be less smoke and soot--thus our feeling that there is less likely to be sooting up of the burner. We had a full tank of what appeared to be clean diesel in the tank of the CD 25. After about 8 hours of use the stove began to smoke badly. I poured out the diesel and put in Kleen Heat--and almost immediately the stove began to behave properly. I supsect that the diesel was old, even though it looked fine.

I agree about the smell, but having lived with a number of diesel engine boats, where the smell was almost always present, it does not bother us.
I would think that the lubricrity would be a greater issue with a high pressure pump--such as the injector pump in a truck or marine engine, where the pressure is close to 1000 PSI. I believe that the Wallas, is basically a lift pump--and limited to about 3 foot lift. I don't know enough to know if the rate of flow of the fuel is determined by the temp of the burner, or just the flow rate (speed or pulses) of the pump.

Pensacola is a seasonal market for Kleen Heat and in the Spring the price is reduced. I usually buy enough in the spring for the next year.

It is my understanding the wallas rate of flow or burner temperature is determined by the flow rate or pump pulses which is controlled on ours by a one to six setting on the rheostat. These pulse flow rates can also be adjusted for more or less flow on the rheostat by adjusting a tiny screw on the controll board. Found this out several years a go when at 8000 feet on Yellowstone Lake and getting to much fuel for air which was causing poor starting. Called Scan Marine and they explained how I could reduce the flow. Believe target was 42 pump pulses per minute on a six or max setting.

The newer truck diesels have injector pump pressures I believe up to 18000 psi which is why they are much more water and lubricity sensitive and with the ULS diesel the oil refiners have added more lub additives. Being not quite sure if it is enough I add year around stanadyne to help even further with this. Maybe Dan knows if what they do add now at the refineries is enough to protect the new higher pressure pumps and injectors from the ULS diesel. I have read some on this and decided not to take the chance at present with the duramax.

We have used Kleen Heat for about six years, with lots of use of the Wallas, and find it a great clean fuel. Once, in TN, we found it on sale (spring shelf cleaning out) at a Home Depot for $1 a jug. We bought out the whole lot!
